Engine cuts out with no warnign after an hour or so
Car: Audi, A4, 2002, 2.0 FSI - Back to Fix-It - Audi Repair Manuals
Q.My Audi A4 2.0 FSI LM03 YNG cuts out with no warnign after an hour or so running a constant journey. The EPC light comes on and she looses power. Leave her for a while and she will start up but same thing will happen again and again until cooled down.
Answer did u get a scan test of the engine computer and the codes ?
i need those to help
Addition Hi I will return with the codes shortly. Thanks for the reply.
Answer SURE JUST LET ME KNOW
Addition Hi, I got the codes from the RAC when they came out.
(1) P1504 -Intake system leak detected (CM$10)
(2) Warm up catalyst efficiency below threshold(bank1) Pending (CN$10)
He checked for air leakes everywhere and could not find one, cleared the codes down and then it went again the next day a couple of times on a long journey home.
If I change gear and take it to the max revs before changing again it then cuts and the CPE light comes on.;Leave it just coast for a minute and then the light goes off and I get power again.
Any suggestions would be welcome.
Thanks
Answer first check the breather valve on the valve cover remove the 4 screws and the 2 tubes take the small end and check if the check valve is closing when u suck and blow if not replace that valve first then clear code and then drive vehicle to see if the converter code comes back
